摘要

摘要: 基于马氏体体积分数对温度偏微分与自由能差对温度偏微分呈线性关系的事实, 提出一种新的马氏体相变动力学模型, 通过与其它马氏体相变动力学模型比较, 并应用于复合材料模型中, 表明本模型与实验结果十分吻合。

Abstract: In this paper, a kinetics model for martensitic transformation in shape memory alloys(SMAs) is established on the fact that the partial derivative of martensite fraction with respect to temperature is in linear relationship with the partial derivative of free energy difference with respect to temperature. The model is compared with Tanaka's model and Liang's model. All the models are implanted in the SMAs reinforced composite model and the result shows that the model established in this paper agrees well with experimental observations.
